If you intend to shoot this thing a lot I suggest you look at a Benelli M2. It has no gas system to puke up and worry about having to get it clean. It also has no little tiny rubber ring to fail just when you need it most. It is hard chrome lined so it wipes clean easily and it has pretty advanced ergonomics to give a really good feel. In addition, it will shoot 2 3/4" and 3" magnum shells.
All that said, I like and respect the Remington 1100. In fact, I just acquired one...but not to shoot. I got it because they sell, and they sell well. I have never understood it and I have tried.
In 1987 Remington came out with the 11-87, which is an updated version of the old 1100. Everyone else was producing guns that would shoot both 2 3/4" and 3" magnums and Remington simply made a version of the 1100 that would shoot both. It is the exact same dimensions and looking at it you cant tell it from a 1100. In fact, the one I shot seemed to kick less with 2 3/4" shells. It never caught on...for some strange reason people cannot get over the 1100. I have tried to figure this out...if the guns are dimensionally the exact same, pretty much identical in mechanics save for the fact that you can shoot both size shells out of one of them, then why not favor that one???? I have yet to hear a valid reason, but believe it or not, that is the way it is.
Have a brand new in the box 11-87 for $500.00 and a clapped out, beat up 1100 right next to it for $750.00 and guess which one some idiot will run up and buy first???? and really think he has got something.....You guessed it, the 1100....go figure!!!!
